Objectives

The student will master the fundamental concepts of numerical methods and will have the ability to perform numerical modeling of technological processes such as casting, bulk metal forming and sheet metal forming, by using commercial codes and related pre and post processing tools.

Program

Characterization of casting and metal forming processes. Different formulations and approaches to solving technological processes by numerical modeling. Finite Difference Method and Finite Element Method. Implicit and Explicit approaches, Static and Dynamic analysis. Application of finite difference and finite element methods to casting and metal forming. Comparison of numerical and experimental results and analysis of possible deviations. Mathematical formulations based in inverse methods. Sensibility analysis by using Adjoint Variable Analysis and Direct Differentiation Method. Optimization algorithms under Updated Lagrangean Method to solve restriction problems as a sequence of unrestricted problems.

Teaching methods and learning activities

Theoretical classes: presentation of every numerical method to use and every technological process to perform numerical modelling.

Applied classes: students are divided by working groups (preferably, every two students for a group) and they will solve and present a work in each of the topics mentioned in the contents of discipline.

Evaluation Type

Distributed evaluation with final exam
